Pay attention to the method of feeding corn to pigs

The practice of feeding pigs with corn alone has proved that for every 1 kg weight gain, more than 6 kg of corn is needed to feed pigs, but only 2.5 kg of corn is needed to feed pigs with formula feed, which can reduce the feeding cost.

Replenish protein feed? Corn has low protein content and poor quality, which can not fully meet the growth needs of pigs. Therefore, protein feed must be supplemented. 15% bean cake or rapeseed cake can be added to pig diet, and 5% fish meal should be added to piglets.

Replenish vitamins? The content of vitamins in corn is low, so it is necessary to add green feed to supplement vitamins. If the lack of green feed, you can add a variety of vitamins for livestock and poultry.

Mineral resupply? The mineral content of corn is low and the nutritional composition is single, so bone meal, calcium hydrogen phosphate, selenium, iron, copper, zinc, manganese and other minerals should be added to pig diet.

Feed after saccharification? After saccharification of corn meal, part of the starch can be converted into sugar, and pigs like to eat and grow quickly. Put the cornmeal into a jar, then pour in 2 times the boiling hot water to make a paste, then sprinkle 5 cm thick dry cornmeal on the surface, and the cornmeal will be saccharified after 3 to 4 hours.

Should you soak before feeding? Soak corn flour with 1: 1.5 times of water for about 2 hours to make corn expand and soften, pigs easy to chew, easy to digest and absorb.
